Special features of Rue
Repels harmful insects
Rue keeps pest bugs away by emitting a strong odor that will camouflage the smell of vegetables. Plant it to repel fruit flies in orchard. Dried leaves act as insect repellant.
Rue has semi-woody branches that make for easy pruning and shaping into a rounded mass. Shows off nicely next to light coloured flowers or as a border. Good in a rock garden.
An attractive pot plant with its blue-green leaves that make a feature. Keep one near your kitchen window to scare flies away.
Attracts useful insects
Butterflies love Rue. Black and giant swallowtails lay their eggs on Rue and their caterpillars feed off it.
Other uses of Rue
Medicinal, insect repellant. A drought-resistant plant that suits coastal or Mediterranean climate gardens. It also can be included in the borders/beds of urban courtyards or wall side borders of cottage gardens.
Although it contains rutin that is good for circulation, research showed that Rue can be dangerous, so it is not really a safe remedy. Essential oils are used in perfume and food flavouring. Red dye.
Leaves are edible, but bitter and also slightly toxic. Should only be used sparingly.
